Titanium has the highest strength to weight ratio. This in effect means that a 6al 4v titanium is suitable for a wide range of applications. Niobium, on the other hand, also suitable for a variety of applications, has several beneficial features for the user. For instance, it has excellent corrosion resistance within concentrated acids and liquid alkaline metals. It is known to be ductile. This makes it good as a ‘chipless forming’ material.
Titanium alloys have been classified into three main categories. These are your alpha, beta and alpha-beta. Alpha alloys are not heat treatable. They do, however, contain neutral alloying elements or alpha stabilizers.
Beta alloys are metastable. They contain enough beta stabilizers. This allows them to retain their beta phase when quenching. They can be treated with solutions. They can be aged to achieve significant increases in strength. The alpha-beta alloys are heat treatable to different degrees, containing a combination of alpha and beta stabilizers. The titanium 6AL 4V is the most common titanium alloy with over fifty percent of total titanium use.
Niobium and its related alloys are used in chemical processing. This includes electronics as part of superconductors, as well as for nuclear technology, acting as reactor components. Electrochemically produced Niobium oxide layers generate what are known as Newton’s rings. Niobium is commonly used in the production of jewelry and metal for coinage.
Lightweight alloys have enough corrosion resistance at high strength at low to moderate temperatures. This makes it suitable for use in medical devices, aircraft parts and components, high performance rate automotive parts and marine and sports equipment. The titanium formula of Ti 6AL 4V is of a higher purity. Because of its excellent biocompatibility, this formula is suitable for use in medical and dental applications.
